kde在“发现者”中改源时,提示没有release文件,默认禁用

kde桌面录音你用啥工具?

Kwave可能是一个选择,它是 KDE 应用程序,应当和 KDE Plamsa 桌面有更好的集成。Kwave手册中关于录音的部分:
Recording (kde.org)
Audacity也是一个选择,虽然它使用了GTK作为它的UI工具箱,可能不太使用于KDE Plasma桌面。Audacity手册中关于录音的快速指南:
https://manual.audacityteam.org/man/record.html

没有录音过。我一般喜欢用simple screen recorder录屏~~

[Kwave]我今天上午做了测试,可以用,但操作起来卡顿感很明显,一个按钮点下去,差不多2秒左右才开始动作; 另外,如果保存为mp3的话,会直接闪退~
[Audacity]我以前一直用,最近换kde后发现它时不时会闪退,还没找到规律,怀疑gtk与qt不和谐有关。因为这个我才测试了kwave。

我找了另一个,qtractor,但因为需要jackd,与现有的冲突,暂还没办法测试~

SSR我一直在用,是现在主要的工具;不过它好像不能只录音频,用来录音的话,需要多一步处理~

你的kde一直很稳定?我的小毛病不断~

jackd与什么相冲突?

根据Kwave 文档,它不支持导出为 mp3 格式。

我也不知道与什么冲突,印象里是,如果使用jackd,会导致当前正在使用的一个啥东西失效,这种情况下,必须保证 jackd可以正常使用,否则两个就都不灵了~

和这是相关的吗?

我试试~

你平时使用什么桌面?

通常是Debian GNU/Linux unstable KDE。

你的unstable kde是用哪个 iso安装的?

使用 https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/daily-builds/sid_d-i/current/amd64/iso-cd/firmware-testing-amd64-netinst.iso ,在安装完成后修改source.list文件。
要直接安装unstable,可以使用 https://mirrors.ustc.edu.cn/debian/dists/unstable/main/installer-amd64/current/images/netboot/mini.iso ,在安装时选择"Advanced options" → “Expert install”,并在选择镜像时选择版本"sid - unstable",参见 Debian Unstable - Debian Wiki

是在虚拟机里用?

我在真机上用。

不稳定性或一些小问题对正常使用有多大影响?

我因为需要生产,所以只使用stable~

参见
https://wiki.debian.org/DebianUnstable
unstable常见的问题在于:

  • 上游错误(通常很快就会被修复)
  • 依赖关系暂时被破坏(这是主要的危险,在更新时必须小心)

论坛上之前有关的讨论:

unstable用户会遭遇到最新的错误(在少见的情况下会导致软件无法使用甚至系统崩溃),更新时依赖关系可能被破坏(特别是在发布后的包迁移期,unstable几乎完全无法更新)。unstable用户应当做好备份并在每次更新时保持高度谨慎,最好安装软件包apt-listbugsapt-listchanges查看软件包的变更和现存问题。unstable是开发快照,虽然存在政策约束,但是不如stable中那么严格。,不建议没有经验的新手使用unstable。
但是只要你能够认真维护,unstable可以正常使用。

I’ve been on Debian Sid as my daily driver work and home for a number of years and it’s basically rock solid. I do get 2 or 3 bugs per year that I need to workaround/report/wait for a fix. Only thing to watch out for, be careful doing apt dist-upgrade, check the “will be removed” section . Some package updates take a number of days to come out, qt libs for example. So a dist-upgrade part way through will try to delete most of qt for example.

再次测试发现,kde软件中心修改源报错,仅限于已经安装的系统;

如果是使用U盘引导的live环境,那么是不会报错的,并且可以从选中的国内服务器安装软件包。

所以,我有一个猜测,就是这个报错( 提示没有release文件,默认禁用 )应该不是一个bug,而是debian有意做成这样:一方面可以让live环境更方便安装软件包来临时测试和使用,另一方面又兼顾了安装后的系统的安全性。http链接有时候确实让人不放心~
